The images show two different types of galapagos tortoises that scientists believe descended from the same species. the first type (left) lives on islands that have high vegetation and few grasses. the second type (right) lives on an island that has large amounts of grasses and low-lying shrubs. what explains the differences in the second turtle's characteristics? a. the environment triggered a gene mutation in neck length to the second turtle survive. b. mutations are random, so the high number of individuals with longer necks is simply by chance. c. turtles with genes for long necks had a better chance of surviving to reach reproductive age. d. turtles with short necks completely lacked adaptations for survival, so they died off.

Ametal ring 4.20 cm in diameter is placed between the north and south poles of large magnets with the plane of its area perpendicular to the magnetic field. these magnets produce an initial uniform field of 1.12 t between them but are gradually pulled apart, causing this field to remain uniform but decrease steadily at 0.240 t/s . (a) what is the magnitude of the electric field induced in the ring? (b) in which direction (clockwise or counterclockwise) does the current flow as viewed by someone on the south pole of the magnet?
